KEY.

Application filed' January 25, 19261- Serial No4 33,630.

E his invention relates to improvements in keys,'the general object of' the invention being to provide the key with a detachable portion v'hich remains in the lock, when the bott ot the saine projected, and thus prevents insertion ci other keys, so that the lock ann-ot be opened by an ordinary key or skeleton key.

another object oi the invention is to so make the key parts that they cannotbe separated until the parts have been adjusted tc project the bolt, so that the detachable portion is either lastened to the ,other por-A tion or to the lock.

- This invention also Consists in certain other Afeatures of construe ion and in the combination and arrangement of the several parts, to be hereinafter fully described, illustratedin the accompanying drawings and specilically pointedr out in the appended claims. y

ln describing mylinvention in detail, referengeV Will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is an elevation oit' the improved key@ Figure 2 is a View of the detachable part, With the tivo portions thereof turned into locking position.

Figure 3 is a View ot the handle part.

Figure 4L is an end view of Figure 2.

Figure 5 is a section on line 5-5 of Figure la Figure 6 is a section on line 6 6 of Figure 5.

Figure 7 is a fragmentary view or the handle part.

As sho-Wn in these views, the key comprises the handle part l, the lock engaging part 2 and the central part 3. The part 3 is of tubular construction and rotatably receives a tubular extension l on part 2 which is held in place by the screw 5 which passes through a hole formed in the wing or lug 3 of said part 3. The part l is provided `with a slot to receive the end of the screiv 5 and this slot is so formed that the parts 2 and 3 can be moved a quarter turn relative to each other. The part 2 is provided with a Wing or lug 2 which is shaped to tit the narrow part of the keyhole of the lock to which the key belongs, and this part- 2 is provided with a bore 6 and a collary 7, the collar acting as a stop 'for preventing` the saidpart beingpushed too far into the lock. This collar 'is termed with the notches 8 and the part Sis provided with similar notches 9. A number ot str-ips "l0 are movably mounted inthe bore (S and are normally held in their projected positionk by the spring ll which is arranged in the bore 6. Each strip is provided with a Wing l2, these Wings being oppositely arranged onrthe two strips shown in the drawings. The Wings engage the notches 8 inthe member 2 but when the member 3 is turned to position its vvingat right anglesfto the vWing of member il, the notches 9 inl said member''` Will be in alignment' With those in member Q, so that the spring 6 Will project the strips l0, and thus cause the wings l2 to engage the notches @which are shalloiver than the'notches 8, so that trie wings will engage both sets ot notches andV thus lock the parts 2' and Btogether.' rllhek outer end oit the part 3 is fil formed .vith ai keyhole 13 for receivingthe Ward 14 on thepart 11,1thisWard being'shaped to iirst: engage oney strip and push it inwardly and then the other strip to push it inwardly. When both strips are pushed inwardly, they Will free the member 3 so that by rotating the part l, the part V2 will be turned to project or retract the bolt of the lock in Which said part 2 is placed', the part 3 being held stationary by the lingers of one hand, or, preferably, by having the extension of its Wing 3 inserted in a port-ion of the keyhole of the lock. The parts l and 3 are so 'formed that when the part l is turned to turn the part 2 to project the bolt of the lock in which said part 2 is placed, the Ward 15 can be pulled from the part 3, but when the parts are in unlocking position, the Ward cannot be Withdrawn from the part '3, so that the entire key assembly is locked together.

From the foregoing, it will be seen that I have provided means for practically plugging up a keyhole When the bolt of the lock is in projected position, so that an ordinary key or a skeleton key cannot be used in an attempt to retract the bolt, as the part 1 is very much smaller than a key which would t the lock. The part l is so small that it can be carried in the pocket Without difficulty and when the parts are in unlocking position, they are locked together so that there is no danger of misplacing the parts. By providing different numbers of the strips l0 and making them of various shapes, the

keys can be made to dilier one from another, so that part l of one key cannot be used for key.

It is thought from the foregoing description that the advantages and novel features oi' my invention Will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes :fall Within the scope of the appended claims.

What l claim is l. A key comprising a handle part having a Ward thereon, a central part and an end part, the latter parts each having a Wing thereon, an extensi on on the end part entering the central part Jfor rotatably connecting the parts together, said parts having notches in their abutting ends, a number of members carried by the .v end'part for engaging the notches for locking the two parts together when their Wings are turned at right angles to each other, spring means for projecting the members and the central part having` a keyhole for receiving the Ward which forces the members out of the slots in the central part.

Q. A key, comprising a handle part having a Ward thereon, a central part-and an end part, the latter parts each having a Wing thereon, an extension on the end part entering the central part for rotatably connecting l fw 1- n l 1 n -1 Y adjusting tne parts 2 and 3 oi another.

remesa the parts together, said parts having notches in their abutting ends, a number of members carried by the end part for engaging the notches for locking the two parts together when their Wings are turned at right angles to'each other, spring means for projecting the members and the central part having a keyhole for receiving the Ward which iforces the members out of the slots in the central part and means for preventing Withdrawal of the Ward when the parts are in unlocking position.

A key of the class described, comprising a handle part having a Ward thereon7 a central part having a Wing thereon provided With an extension to enter a part of the keyhole of the lock, said central part having a keyhole for receiving the Ward, the parts being formed to prevent Withdrawal of the Ward When the handle part is turned, an end part having a Wing thereon for engaging the keyhole of the lock and a shoulder for limiting the movement 0i the part in the lock, said central part and end part having notches in their abutting ends, Winged members in said parts With the Wings engaging the notches, a spring for projecting the Wing members and said members having their ends shaped to engage different portions of the Ward so that said members will be moved by the Ward at diliferent times.

ln testimony whereof I affix my signature.

ROBERT TOENNIGES.
